This. I think TOR decided to go with a very annoying interpretation, because they said "If we make the Sith all about Passion, we can have Jedi's be the total opposite"

And the Jedi order isn't against emotion. It teaches controlling them, thus the rules they have, because a force user who can't control their emotions is a dangerous individual. More dangerous than a pissed off smuggler/bounty hunter with a blaster.

Of course that's a little hard to convey in a game where they want to make every player equal. It's the difference between the Star Wars storyline and making Star Wars a game.

Exactly! Well said. That is a great point about the danger of a force-user who can't keep their emotions in check. So they know how to handle them. So someone in the Jedi Order (Padawan, Knight, Master) doesn't "fly off the handle" while having the ability use the Force at the same time.
